Abstract

The present invention provides an image forming apparatus that has unfixed image forming device for forming an unfixed image based on an image formation start signal, and fixing device for fixing the unfixed image (4), formed by the unfixed image forming device, on a recording material (5), wherein the fixing device includes a rotating member (1) and magnetic flux generating device (7) for generating a magnetic flux by supplying power, wherein the magnetic flux generated by the magnetic flux generating device generates an eddy current in the rotating member, so that the rotating member generates heat, thereby an image on the recording material is heated, and wherein, in a stand-by state prior to an input of the image formation start signal, a rotation of the rotating member is stopped and the magnetic flux generating device is energized.
